appntion mea my 5,

To all whom# concern:

Be it known that I, PETER G. JAcoBsoN, citizen of the United States,'residing at and State of'Illinois, have invented a certain new anduseful Improvement in Condensers, of which the following. is a full,clear, concise, and

exact description.

My invention relates to electrical condensers and has for its object theprovision of improved means for effecting the assemblyo-f the leaveswhich comprise the sides thereof.

In accordance with one characteristic of the invention there' is amounting sleeve having a plurality of sets of arcuate slots distributedalong the sleeve, the leaves of one condenser side entering said slotsand being recessed to receive the unslotted portion of the sleeve whichis formed with interleaving fingers that margin the slots therein. Thesefingers are preferably of wedge formartion whereby they exert'pressureupon each other longitudinally of the sleeve upon con' traction of thefingers. The spaces between the fingers extend through the material ofthe sleeve or tube into communication with the bore of the sleeve ortube.

In accordance with another characteristic of the invention the leaves ofthe other condenser side vare rovided with a mounting rod and alongitudinally split sleeve embracing said rod and formed withtransverse fingers between which portions of these leaves are re` ceivedwhereby they are assembled with said Y rod. The leaves are desirablyprovided with aligned recesses through which the mounting rod is passed,there being fingers upon opposite sides of the split in the sleeve sothat portions of the leaves which margin both sides of the recessestherein may be received between the fingers upon the sleeves.

There are preferably three such rods associated as described.

I will explain my invention more fully by referencev to the accompanyingdrawing in which Fig. 1l is a view in elevation, partially in section,of a condenser constructed in accordance with the preferred embodimentofthe invention; F1g. 2 is a sectional view on line 2--2 of Fig. l 1; Fig.3 illustrates some of the condenser leaves of one .condenser side andparts for assembling the same; Fig. 4 1s a view showing the sleeveoffngered formation and some of the condenser leaves assembledtherewith; Fig. 5

illustrates some of the condenser leaves of the other condenser side andthe fingered sleeve for assembling the same, one condenser leaf beingshown in assembly with the sleeve and another in and Fig. 6 is anenlargement of a portion of n 1g. 2 but before the split sleeve shown inthis figure has been clinched into engagement with the rod passingtherethrough, the clincning of the sleeve being indicated by dottedlines.

Like parts are indicated by similar characters of reference throughoutthe different figures.

The condenser illustrated includes two mounting plates l and 2 ofinsulating material which are assembled upon threaded metallic rods3 bymeans of nuts 4, 5, 6 and 7. These rods are assembled with the mountingboard 8, there being distance preserving sleeves 9 that intervenebetween the nuts 4 andthe insulating plate 1. One of the con- 'densersides is composed of a group of metallic leaves 10 yformed with alignedU- shaped recesses 11 through which the mounting. rods 3 pass, therebeing preferably three such mounting rods. A longitudinally splitmetallic sleeve or tube v12 embraces each rod 3 and is' formed withtransverse fingers 13 upon opposite sides ofthe split in the sleeve,these fingers entering the spaces between the leaves. The spaces orslots 14 between the fingers communicate with the interiors or bores ofthe sleeves andvsnugl receive the portions of the leaves which7 marginthe sides of the recesses 11 therein. In the process of assembly thesplit sleeve 12 is preferably initially of U-form as indicated in Figs.3 and 6, the ends of the fingers being-clinchedinto engagement with thecorresponding rod after the sleeve has been placed upon thecorresponding rod with the sides of the recessll in the slots Abetweenthe fingers thereof.

The other condenser side'com rises leaves 15 which are interleaved withti e leaves 10 and a metallic mountin sleeve 16. This mountingvsleevehas .aA urality of sets of arcuate slots distributed along the sleeve,there being three arcuate slots 17, 18 and 19 in each set that arearranged circumferenseparated relation;

Each sleeve is thus middle slot 18 of each circumferential set and Wingportions 23, 24 which respectively enter the end slots 17, 190i suchset. T-he sleeve is formedwith .a set of fingers 25 upon one side, a setof fingers 26 upon the y other side, the fingers of one set interleav-ling with the fingers of the otherA and the fingers of both sets taperingor otherwise formed to exert pressure upon one another longitudinally ofthe sleeve upon contraction of the ngers whereby the portions of theplates that are in the arcuate slots between the fingers are grippedinto firm as` sembly with the sleeve.

threaded upon the other end of the shaft 28 and presses against theadjacent end of the mounting sleeve whereby the assembly of the mountingsleeve and shaft is completed. The shaft 28 projects through themounting plate 2. A knob 32 has a stern 33 which is threaded upon theprojecting front end of the shaft 28. The stem 33 serves to hold thebearing portion 34 between it and the nut 31 this bearing portionturning within the plate 2'. There is a rotative mounting for the`mounting sleeve when the condenser Side=carried by the mountingsleeveis to be adjustable, but the invention is not to be thus limited. vWhile I ha've herein shown and particularly described the preferredembodiment of my invention I do not wish to be limited to the precisedetails of construction shown as changes may readily be made Without de-1 arting from the siprit of my invention, but avingv thus described myinvention I claim as new and desire to cure by Letters Patent thefollowing:
